“PowerPoint makes us stupid,” Gen. James N. Mattis of the Marine Corps, the Joint Forces commander, said this month at a military conference in North Carolina. (He spoke without PowerPoint.) Brig. Gen. H. R. McMaster, who banned PowerPoint presentations when he led the successful effort to secure the northern Iraqi city of Tal Afar in 2005, followed up at the same conference by likening PowerPoint to an internal threat

Richard C. Holbrooke, the Obama administration’s special representative for Afghanistan and Pakistan, was given PowerPoint briefings during a trip to Afghanistan last summer at each of three stops — Kandahar, Mazar-i-Sharif and Bagram Air Base. At a fourth stop, Herat, the Italian forces there not only provided Mr. Holbrooke with a PowerPoint briefing, but accompanied it with swelling orchestral music.

President Obama was shown PowerPoint slides, mostly maps and charts, in the White House Situation Room during the Afghan strategy review last fall.

Commanders say that the slides impart less information than a five-page paper can hold, and that they relieve the briefer of the need to polish writing to convey an analytic, persuasive point. Imagine lawyers presenting arguments before the Supreme Court in slides instead of legal briefs. (emphasis added)
